When is a person said to have developed cataract in his eye? How is the vision of a person having cataract restored?
A person is said to have developed cataract, when the eye lens becomes progressively cloudy or opaque. It causes blurred vision, and may eventually lead to complete loss of vision.
The vision of a person having cataract can be restored by the surgery in which the opaque lens is removed, and a new artificial lens is inserted in its place.
Explanation
Cataract is a defect of the eye in which the eye-lens of a person become progressively cloudy or opaque resulting in blurred vision.
It usually comes in old age and develops due to the formation of a membrane (clumps of protein) over the eye-lens.
It can't be corrected by any type of spectacles lenses, rather it can be corrected by the surgery in which the opaque lens is removed, and a new artificial lens is inserted in its place.
